The mayor read report from the
special committee on street lights:
Rock ISLAND, Ill. Sept 5. 1887
To the Mayor and City Council:
GENTaENEN-The committee on lights
aud lighting OF streets aud alleys OF the
cuy by electricity, respectfully submit
for your consideration the following re
port.
There are two methods Of lighting BY
electricity, one known us the arc light
the other as the incandescent light
Lighting with the arc light is usually
done by means OF towers of Il height
varying from l35 feet To 200 feet, or by
mast or arm, VARYING in height from q
feet 10 80 feet, and IN some instances hY
a combination, towers being placed in
certain localities and masts placed at IN
tnrvulS whom fbp t1ynr iisbt T.,
she distance of reflection becomes toe
dim to be ciIcclual for lighting purposes
Arc lights may he furnished of different
intensity, but past experience in greai
maiOrity of cities where 1t was used fol
street lighting indicates that a 2oUt
candle power is preferable to any othe
degree of intensity FOR street purposes
IncandesCent lights for lighting street:
may be furnished OF is, %. SO and II
candle power and probably of still
greater power, In the case of incandes
cent lights towers are not used, the wire
and lights being placed on posts of mod
crate height in somewhat similar man
ner to the mast lights, but of create
number and at shorter intervals. Theo
reticalIV, the system of lighting by ar
light is to furnish the necessary light b.
- group of lights Of high candle powe
located at the top OF towers and as near
as possible arranged IN triangular order

system the towers are comparatively few

For lighting the streets and alleys O

three propositions:
